Q:
The menu doesn't show the drop down sub items. If you would look at the script there are two
sublinks for Accommodation which however is not visible when we are
doing a mouse over. I attaching the data.js file with
my mail. Please let me know if thre is anything else hat i need to
look into my drop down menu scripts.

A:
You should set back color for your submenus.

For example you should create style and assign it for the subitems:
var itemStyles = [
["itemBackColor=#61420A,#B77D13","itemBorderWidth=1","itemBorderStyle=solid,solid",,"itemBorderColor=#3C2906,#3C2906"],//style0
];
